Author of the number one selling textbook in comparative endocrinology, Vertebrate Endocrinology, tenor David O. Norris has sung with Cantabile for over 20 years.

A native of Ohio, David has a PhD from the University of Washington in Zoology (Endocrinology). He has worked at CU Boulder since 1966 as Professor of Biology (1966–2004), Professor (2004–2012) and Professor emeritus (2012–present) in the department of Integrative Physiology.

David is allergic to rodents and so for more than 50 years he studied fishes and amphibians as model organisms to learn how environmental factors (including man-made chemicals) alter the secretion of our hormones. He discovered that estrogenic chemicals released from the Boulder wastewater treatment plant were feminizing fishes downstream (a phenomenon since shown around the country). He is a member of the Board of Directors of The Endocrine Disruption Exchange.

He developed techniques using gastrointestinal contents to help determine time of death and connect suspects to crime scenes by using microscopic examination of plant remains. David is a charter member of NecroSearch International, a volunteer group of law enforcement personnel and scientists that locate clandestine graves.

His pet peeves include choral directors who say “that was good” when it really wasn’t, out-of-tune singing and corporations that are clearly interested only in profit at the expense of the environment and of people.
